WhatsLedger is a spending tracker and bill splitter that lives inside WhatsApp. Nothing to download and no sign-up, your phone number is your account. After a group dinner, one person usually pays and then has to chase everyone for who had what and how much. With WhatsLedger the payer sends a photo of the receipt with the word “split”. The bot reads every item and checks that they add up to the total before saving anything. The payer then forwards one message to the group. Each friend replies with the numbers of the dishes they had (or select them on a simple web app), and shared dishes are split with one tap. When everyone’s in, the bill closes and each person gets a message for exactly what they owe. They tap “I’ve paid” and the payer is told right away. It’s also an everyday ledger. You can log an expense by typing “coffee 4.50” or sending a voice note, then ask things like “how much did I spend on food this month?” or “can I afford a 300 hotel?” and get answers from your own data. Region packs are picked by phone number, so a +65 number gets SGD, local food words and PayNow (Singapore's QR wallet transfer), and a +60 number gets Malaysian ringgit. Anything that works better as a list, like the dashboard, opens as a signed web page in one tap. The goal is fewer steps for everyone, the payer and the friends.
